The actuation of the film advancing mechanism by the operating lever 8 and its associated ring 5 is illustrated particularly in Fig. 2. There -is arranged coaxially with the ring 5 and rotatable withthe same a toothed segment 22 engaging a gear 23 mounted rotatably on a horizontal shaft 24. A pawl 25 pivotally secured on the gear 23 is urged by a spring 26 in engagement with a ratchet wheel 21 to rotate the same in one direction only, namely when the lever 8 is manually depressed. The ratchet wheel 21 is fixedly secured to the shaft 24 which; has also secured thereon the bevel gear 28 meshing with a bevel gear 29 on a vertical shaft 30. This shaft 30 has the film conveying roller 8 fixed thereto. The lower end of the vertical shaft.30 has a spring 3| applied thereto which preventsa reverse rotation of the roller 8 when the operating lever B and therewith the gearing 22, '23 returns to initial position; v

The shaft 30 is connected by gears 32, 32 and 33 with the shaft 34 on which the film take-up spool'33 is rotatably mounted. The spool 35 is driven by the shaft 34 by the intermediary of a friction clutch 36. Whenever the operating lever B is depressed the film conveying roller 8 is set in motionto unwind the film from the supply spool 38 and to drive the spool 35 upon which the film isto be wound. a

' The Fig. 2' illustrates also a counting device which indicates the number of exposures taken with the camera. This counting device includes a toothed annular disc 40 mounted rotatably within the casing portion 2 coaxial with the finder lens 3 *and directly adjacent the inner face of the front-wall 4. The forward directed face 01' the annular disc 40' is provided with a series oi! numbers or thelike, indicating exposures. One of these numbers at the time is made visible through a window opening 4lin the wall 4, preferably just above the finder lens 3 as shown in Fig.2. The disc 40 is rotated step by step by a pawl 42 whenever the'operating lever 8 is manually. operated to tension the shutter and to ad- Vance the film one complete picture area. This pawl 42 is pivotally attached at 48 to a radial projection 43 of the ring 5 and by a spring 44 is urged in a directimon toward the toothed circumierence of the disc 40. The pawl 43 normally rests with its disc-enaging endv upon a stationary cam member 45 concentric with the disc 40. Only during the last portion of the downward movement of the operating lever 8 the pawl 43 leaves the cam member 45 and engages the toothed circumlerence of the disc 40 to rotate the latter one step sothat the next number will appear in the windowopening 4|.

The operation of the camera of the invention, .as far as the tensioning of the shutter, the ad- .vancement of the film and the release 01' the shut- .ter are concerned is believed to be obvious. .All these operations. can be accomplishedwhile the camera is held in both hands and faces the object to be photographed, ready for taking the picture.
